p-0002This application claims priority to U.S. Provisional Application No. 61/603,261 entitled “INTELLIGENT SPECTRUM ALLOCATION BASED ON USER BEHAVIOR PATTERNS FOR EFFICIENT SPECTRUM USAGE,” filed Feb. 25, 2012, the entire disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND

p-00031. Field of the Disclosed Embodiments

p-0004The present invention relates generally to wireless communications and more particularly to an approach for policy-driven spectrum allocation and sharing of multiple workloads in a distributed computing environment.

p-00052. Introduction

p-0006Service providers and device manufacturers (e.g., wireless, cellular, etc.) are continually challenged to deliver value and convenience to consumers by, for example, providing compelling and reliable network services. Spectrum consumers like to get the data anytime and anywhere—that is have reliable service. However, with data explosion that becomes harder to achieve for operators. Numerous organizations have forecast significant mobile broadband traffic growth over the coming 5-10 years worldwide. On average, those forecasts approach 80% compound annual growth rate. This high traffic growth leads to the conclusion that spectrum (current and planned) targeted for exclusive licensing by mobile broadband carriers could be exhausted before the end of the decade. On the other hand, in spite of the potential spectrum scarcity problem, spectrum utilization measurements in most countries, worldwide, have shown that there is a large amount of underutilized spectrum in the 300 MHz to 6 GHz range. Industry and regulatory agencies are aware of these facts and issues, and are thereby trying to adopt more flexible and dynamic regulatory framework to enable spectrum sharing or access, which is called Dynamic Spectrum Sharing (DSS) and Dynamic Spectrum Access (DSA), respectively. DSS and DSA may enable a secondary user or spectrum holder in need of spectrum availability to use spectrum assigned to, or owned by, a primary user or spectrum holder without any harmful interference.

p-0007Cloud Spectrum Services (CSS) is a framework for Dynamic Spectrum Sharing (DSS) and Dynamic Spectrum Access (DSA) using the cloud for spectrum management that provides optimum spectrum allocation through dynamic spectrum rentals. At the heart of the CSS framework there is a CSS database and a broker that manages and optimizes the allocation based on various inputs like device capability, base station capability, spectrum availability and user needs, user movement and the like.

p-0036<figref idrefs="DRAWINGS">FIG. 1</figref> is a diagram of a system <b>100</b> capable of managing dynamic sharing of available spectrum services, according to one embodiment. System <b>100</b> is capable of managing dynamic sharing of available spectrum services. For instance, the system <b>100</b> addresses the need for interfaces and protocols that enable communications among entities such as primary spectrum holders, alternate spectrum holders, spectrum brokers or management services, and/or regulatory agencies to facilitate dynamic sharing of available spectrum services by way of a cloud interface.

p-0037There are four major stakeholders in CSS: 1) a primary spectrum service holder having an exclusive right to use a specific spectrum service, 2) an alternate spectrum holder, e.g. a cellular or mobile broadband operator or service provider that may need to rent or borrow pieces of the spectrum owned or assigned to the primary spectrum service holder, 3) a regulatory agency that manages spectrum allocation and/or authorizes a renting or sharing deal between the primary spectrum service holder and the alternate spectrum service holder, and 4) a spectrum broker or management service that manages CSS transactions performed in the CSS cloud.

p-0038As shown in <figref idrefs="DRAWINGS">FIG. 1</figref>, the system <b>100</b> comprises user equipment (UE) <b>101</b><i>a</i>-<b>101</b><i>n </i>(collectively referred to as UE <b>101</b>) having connectivity to a CSS management platform <b>103</b>, one or more primary spectrum service holders <b>107</b><i>a</i>-<b>107</b><i>n </i>(collectively referred to as primary spectrum service holder <b>107</b>), one or more alternate spectrum service holders <b>109</b><i>a</i>-<b>109</b><i>n </i>(collectively referred to as alternate spectrum service holder <b>109</b>), a CSS database <b>111</b>, and one or more a spectrum service allocation regulators (collectively referred to and illustrated as spectrum service allocation regulator <b>113</b>) via a communication network <b>105</b>. While all of the UE <b>101</b>, CSS management platform <b>103</b>, primary spectrum service holder <b>107</b>, alternate spectrum service holder <b>109</b>, CSS database <b>111</b> and spectrum service regulator <b>113</b> are all illustrated as having connectivity to the communication network <b>105</b>, each of these features may or may not have direct connectivity to one another, according to various embodiments and system architectures.

p-0039According to various embodiments, the CSS management platform <b>103</b> may be operated by a spectrum broker or management service and be operatively connected to, or include, the CSS database <b>111</b> like shown in <figref idrefs="DRAWINGS">FIG. 3</figref>. The CSS management platform <b>103</b> may also be configured to store various computational resources to perform CSS transactions in the CSS database <b>111</b> or in another memory associated with the CSS management platform <b>103</b>.

p-0040According to various embodiments, the infrastructure of the alternate spectrum service holder <b>109</b> may be a radio access network (RAN) and/or a core network that has a capability to use various available spectrum services provided by the primary spectrum service holder <b>107</b> as rental spectrum, for example. Additionally, the UE <b>101</b> may be a CSS-capable multi-mode device (MMD), for example, capable of using various available spectrum services provided by the primary spectrum service holder <b>107</b>.

p-0041In one or more embodiments, there may be any combination of one or more of the following four logical interfaces. For example, a first interface is defined between the primary spectrum service holder <b>107</b> and the CSS database <b>111</b>. A second interface is defined between the alternate spectrum service holder <b>109</b> and the CSS management platform <b>103</b>. A third interface is defined between the CSS management platform <b>103</b> and the CSS database <b>111</b>. A fourth interface is defined between the primary spectrum service holder <b>107</b> and CSS management platform <b>103</b>.

p-0042According to various embodiments, depending on CSS architecture, there may also, or alternatively, be other logical interfaces defined between the CSS management platform <b>103</b> and the UE <b>101</b>, and/or the spectrum service allocation regulator <b>113</b>. Or, the spectrum service allocation regulator may directly interface with the primary spectrum service holder <b>107</b>.

p-0043In one or more embodiments, the primary spectrum service holder <b>107</b> provides the CSS management platform <b>103</b> and/or the CSS database <b>111</b> directly or by way of the CSS management platform <b>103</b> information, for instance, regarding which spectrum services such as radio resources are available for a particular period of time on a dynamic basis. The information regarding available spectrum services provided by the primary spectrum service holder <b>107</b> is accordingly stored in the CSS database <b>111</b>.

p-0044According to various embodiments, the alternate spectrum service holder <b>109</b> or the UE <b>101</b> provides the CSS management platform <b>103</b> via an interface with one or more spectrum sharing requests regarding spectrum renting. For example, if the alternate spectrum service holder <b>109</b> or the UE <b>101</b> determines that additional spectrum services are needed beyond those currently available to the alternate spectrum service holder <b>109</b> or the UE <b>101</b> or estimated as being available in the future to the alternate spectrum service holder <b>109</b> or the UE <b>101</b>, the alternate spectrum service holder <b>109</b> or the UE <b>101</b> makes a request for spectrum sharing that is sent to the CSS management platform <b>103</b> so that a need for current or future spectrum services may be satisfied.

p-0045Additionally, an operator database <b>110</b> is shown coupled to or residing at each or in one of the alternate spectrum service holder. The operator database <b>110</b> is capable of performing the same functions as CSS database <b>111</b>. Operator database <b>110</b> receives dynamic spectrum availability information from spectrum broker identifying the primary holder and spectrum asset descriptors such as time, bandwidth, terms of use, price, and location. The availability information may be formatted to any suitable database structure and may be stored by a memory. A tabular form of the spectrum availability information is shown as table <b>126</b>. The table <b>126</b> lists the primary spectrum holder <b>127</b> and the spectrum asset descriptors <b>128</b>. In addition to collecting and organizing spectrum information, operator database <b>110</b> may maintain spectrum rules or inference engine to manage rules for spectrum use, including rules established by the primary spectrum holder <b>107</b>, government regulations, or agreed upon rules established by the parties. In a tree structure CSS database <b>111</b> would be the root node (parent) while all the operator databases would be a branch or child of the database <b>111</b>.

p-0046For example, the request for spectrum sharing may specify various service criteria or details regarding the request such as, but not limited to, one or more of a period of time during which the requested spectrum sharing is to occur, a price offering range for the requested spectrum sharing, a frequency range within which the requested spectrum sharing is allowed to occur, a performance requirement associated with the source of the request for spectrum sharing, and a spectrum service holder with which the requested spectrum sharing is allowed to occur.

p-0047The primary spectrum service holder <b>107</b>, along with the information regarding which spectrum services are available, may indicate various spectrum sharing criteria to CSS management platform <b>103</b> regarding renting conditions including, but not limited to, an asking price for sharing an available spectrum service, a performance data of the available spectrum service, a frequency range of the available spectrum service, and a spectrum sharing requestor with which the available spectrum service is allowed to be shared.

p-0048Based on a receipt of a request for spectrum service sharing, the CSS management platform <b>103</b> obtains information stored in the CSS database <b>111</b>, and analyzes the alternate spectrum service holder <b>109</b>'s or the UE <b>101</b>'s requests for spectrum sharing, and may also consider any regulatory rules that are provided by the spectrum service allocation regulator <b>113</b> to cause an allocation of one or more available spectrum services to the alternate spectrum service holder <b>109</b> or the UE <b>101</b>.

p-0049For example, the CSS management platform <b>103</b> may compare the various spectrum sharing criteria set by the primary spectrum service holder <b>107</b> with the service criteria provided by the alternate spectrum service holder <b>109</b> or the UE <b>101</b>. Based on this comparison, the CSS management platform <b>103</b> may determine whether a particular available spectrum service should be shared with the requesting alternate spectrum service holder <b>109</b> or the UE <b>101</b>. The determination to share the available spectrum service may be based, for example, on a matching between the spectrum sharing criteria stored in the CSS database <b>111</b> and the service criteria provided by the alternate spectrum service holder <b>109</b> or the UE <b>101</b>. The matching may be based on an optimization routine associated with pairing the various spectrum sharing criteria and the various service criteria, for example. Then, based on the matching, a decision to share an available spectrum service stored in the CSS database <b>111</b> may be made and the available spectrum service may be allocated to the alternate spectrum service holder <b>109</b> or the UE <b>101</b>.

p-0050For example, if a primary spectrum service holder <b>107</b> only wants to enable sharing/renting of its available spectrum services to certain competitor carriers at particular times, the CSS management platform <b>103</b> causes a decision to share available spectrum services to be made in accordance with that particular combination of spectrum sharing criteria. Or, for example, if a primary spectrum service holder <b>107</b> will only rent or share its available spectrum services for a particular minimum price, the CSS management platform <b>103</b> will only match an alternate spectrum service holder <b>109</b> or UE <b>101</b> that has a price offering that meets the asking price provided in the spectrum sharing criteria. According to various embodiments, the CSS management platform <b>103</b> may be configured to maximize the revenue produced by sharing available spectrum services. For example, if an alternate spectrum service holder <b>109</b> or a UE <b>101</b> provides service criteria including a price offering or a price range that exceeds the asking price for spectrum rental, the CSS management platform <b>103</b> will allocate the available spectrum services to the highest bidder (assuming multiple bidding alternate spectrum service holders <b>109</b> or UE <b>101</b>'s, for example) and/or, if there is only one bidding entity, will allocate the available spectrum service at the maximum of the offered range, rather than at the asking price which may be lower than the offered range.

p-0051In one or more embodiments, the various spectrum sharing criteria and/or the service criteria may be weighted such that certain criteria is more important than other criteria, so that the decision to share spectrum services may be based on a weighted matching. For instance, if a spectrum sharing criteria is set to be limited to a particular time has a weighting of “X”, but a price point for spectrum sharing is set as “Y” which is more heavily weighted than X, and a particular price point offered by the alternate spectrum service holder <b>109</b> or the UE <b>101</b> causes the timing limit to be overridden, the CSS management platform <b>103</b> may cause a decision to share the available spectrum service based on the price offering even though the primary spectrum service holder <b>107</b> would normally not allow spectrum sharing during the time at which the request for sharing spectrum services is made or the time at which the spectrum sharing is to occur. In other words, if a primary spectrum service holder <b>107</b> does not want to share spectrum services with a competitor such as alternate spectrum service holder <b>109</b> or UE <b>101</b> during peak hours, the primary spectrum service holder <b>107</b> may do so if the price is right.

p-0052It should be noted that the above examples are merely exemplary regarding potential matching, alignment, weighting, optimization and/or reasoning for comparing and matching an alternate spectrum service holder <b>109</b> or UE <b>101</b> with an available spectrum service provided by primary spectrum service holder <b>107</b>. Any type of data or criteria, combination, or weighting scheme for spectrum sharing and/or service criteria may be provided to the CSS management platform <b>103</b> for consideration when making a determination to share available spectrum services and when allocating available spectrum services to an alternate spectrum service holder <b>107</b> and/or a UE <b>101</b>.

p-0053Additionally, the CSS management platform <b>103</b> may consider any regulatory rules provided by the spectrum service allocation regulator <b>113</b>, or rules could be integrated into CSS database <b>111</b>, when determining to share the available spectrum service with the requesting alternate spectrum service holder <b>109</b> or the UE <b>101</b>. For example, any regulatory rules that govern allocation of spectrum services by way of rental, borrowing, sharing, etc. may be considered when the CSS management platform <b>103</b> optimizes the matching of spectrum sharing criteria and service criteria, or the CSS management platform <b>103</b> may apply the regulatory rules after a determination to share the available spectrum services is made and the regulatory rules are applied to approve or disapprove of the decision to share the available spectrum services and/or the allocation of the available spectrum services to the alternate spectrum service holder <b>109</b> or the UE <b>101</b>.

p-0054In one or more embodiments, the CSS management platform <b>103</b> updates the CSS database <b>111</b> regarding the allocation of the available spectrum services to the alternate spectrum service holder <b>109</b> or the UE <b>101</b>. The CSS management platform <b>103</b> may also advise the alternate spectrum service holder <b>109</b> or the UE <b>101</b> of a decision on their request for spectrum sharing by way of a notification message. The notification message may include specific details regarding the decision to share the available spectrum service and/or the allocation such as price paid, price to be paid, time for the allocation, frequency allocation, primary spectrum service holder details, etc.

p-0055The CSS management platform <b>103</b> may also report the allocation of the available spectrum service to the primary spectrum service holder <b>107</b> by way of a notification message. The notification message may include specific details regarding the decision to share the spectrum service and/or the allocation such as price paid, price to be paid, time for the allocation, frequency allocation, primary spectrum service holder details, etc.

p-0056By way of example, the communication network <b>105</b> of system <b>100</b> includes one or more networks such as a wired data network, a wireless network, a telephony network, or any combination thereof. It is contemplated that the data network may be any local area network (LAN), metropolitan area network (MAN), wide area network (WAN), a public data network (e.g., the Internet), short range wireless network, or any other suitable packet-switched network, such as a commercially owned, proprietary packet-switched network, e.g., a proprietary cable or fiber-optic network, and the like, or any combination thereof. In addition, the wireless network may be, for example, a cellular network and may employ various technologies including enhanced data rates for global evolution (EDGE), general packet radio service (GPRS), global system for mobile communications (GSM), Internet protocol multimedia subsystem (IMS), universal mobile telecommunications system (UMTS), etc., as well as any other suitable wireless medium, e.g., worldwide interoperability for microwave access (WiMAX), Long Term Evolution (LTE) networks, code division multiple access (CDMA), wideband code division multiple access (WCDMA), wireless fidelity (WiFi), WiGig, wireless LAN (WLAN), Bluetooth®, Internet Protocol (IP) data casting, satellite, mobile ad-hoc network (MANET), and the like, or any combination thereof.

p-0057The UE <b>101</b> is any type of mobile terminal, fixed terminal, or portable terminal including a mobile handset, station, unit, device, multimedia computer, multimedia tablet, Internet node, communicator, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, personal communication system (PCS) device, personal navigation device, personal digital assistants (PDAs), audio/video player, digital camera/camcorder, positioning device, television receiver, radio broadcast receiver, electronic book device, game device, or any combination thereof, including the accessories and peripherals of these devices, or any combination thereof. It is also contemplated that the UE <b>101</b> can support any type of interface to the user (such as “wearable” circuitry, etc.).

p-0058By way of example, the UE <b>101</b>, CSS management platform <b>103</b>, primary spectrum service holder <b>107</b>, alternate spectrum service holder <b>109</b>, and optionally CSS database <b>111</b> and spectrum service allocation regulator <b>113</b> communicate with each other and other components of the communication network <b>105</b> using well known, new or still developing protocols. In this context, a protocol includes a set of rules defining how the network nodes within the communication network <b>105</b> interact with each other based on information sent over the communication links. The protocols are effective at different layers of operation within each node, from generating and receiving physical signals of various types, to selecting a link for transferring those signals, to the format of information indicated by those signals, to identifying which software application executing on a computer system sends or receives the information. The conceptually different layers of protocols for exchanging information over a network are described in the Open Systems Interconnection (OSI) Reference Model.

p-0059Communications between the network nodes are typically effected by exchanging discrete packets of data. Each packet typically comprises (1) header information associated with a particular protocol, and (2) payload information that follows the header information and contains information that may be processed independently of that particular protocol. In some protocols, the packet includes (3) trailer information following the payload and indicating the end of the payload information. The header includes information such as the source of the packet, its destination, the length of the payload, and other properties used by the protocol. Often, the data in the payload for the particular protocol includes a header and payload for a different protocol associated with a different, higher layer of the OSI Reference Model. The header for a particular protocol typically indicates a type for the next protocol contained in its payload. The higher layer protocol is said to be encapsulated in the lower layer protocol. The headers included in a packet traversing multiple heterogeneous networks, such as the Internet, typically include a physical (layer 1) header, a data-link (layer 2) header, an internetwork (layer 3) header and a transport (layer 4) header, and various application (layer 5, layer 6 and layer 7) headers as defined by the OSI Reference Model.

By way of example, the CSS management platform <b>103</b> includes one or more components for managing a dynamic sharing of available spectrum services. It is contemplated that the functions of these components may be combined in one or more components or performed by other components of equivalent functionality. In this embodiment, the CSS management platform <b>103</b> includes a communication module <b>203</b>, a control logic <b>201</b>, a sharing decision module <b>205</b>, a regulatory rules module <b>207</b>, an allocation module <b>209</b>, and optionally the CSS database <b>111</b>, discussed above.

p-0061According to various embodiments, the CSS management platform <b>103</b> receives information regarding one or more available spectrum services provided by the primary spectrum service holder <b>107</b> by way of the communication module <b>203</b>. The control logic <b>201</b> causes the information regarding the one or more available spectrum services to be stored in the CSS database <b>111</b>. A request for spectrum sharing may be received by the communication module <b>203</b>. Upon receipt of the request for spectrum sharing, the control logic <b>201</b> instructs the sharing decision module <b>205</b> to assess any information associated with the request for spectrum sharing such as service criteria discussed above and/or the source of the request for spectrum sharing such as alternate spectrum service holder <b>109</b> or UE <b>101</b>. The sharing decision module <b>205</b> accordingly compares the information associated with the request for spectrum sharing with any information associated with the available spectrum services stored in the CSS database <b>111</b> such as, but not limited to, any spectrum sharing criteria and/or any regulatory rules managed by the regulatory rules module <b>207</b> to determine to share one or more of the available spectrum services with the source of the request for spectrum sharing.

p-0062As discussed above, the decision to share spectrum services may be made inclusive of any available regulatory rules or be made before any regulatory rules are applied to verify a decision to share the available spectrum services. Upon making a decision to share one or more available spectrum services, the control logic <b>203</b> causes the allocation module <b>209</b> to facilitate sharing of the available spectrum services by allocating one or more available spectrum services to the source of the request for spectrum sharing, i.e. the alternate spectrum service holder <b>107</b> or the UE <b>101</b>.

p-0063Upon allocating the available spectrum services to the source of the request for spectrum sharing, the allocation module <b>209</b> notifies one or more of the primary spectrum service holder <b>107</b> and the alternate spectrum service holder <b>109</b> or the UE <b>101</b> that the allocation has occurred and may also indicate various details related to the decision to share the one or more available spectrum services such as price, time, provider, etc. by way of the communication module <b>201</b>. Additionally, the allocation module <b>209</b> causes the CSS database <b>111</b> to be updated to reflect the allocated spectrum services. CSS database <b>111</b> receives dynamic spectrum availability information from the PSH identifying the primary holder and spectrum asset descriptors such as time, bandwidth, terms of use, price, and location. The availability information may be formatted to any suitable database structure and may be stored by a memory. A tabular form of the spectrum availability information is shown as table <b>126</b>. The table <b>126</b> lists the primary spectrum holder <b>127</b> and the spectrum asset descriptors <b>128</b>.

p-0064<figref idrefs="DRAWINGS">FIG. 3</figref> provides an overview <b>300</b> of the concept behind Cloud Spectrum Services (CSS) with distributed computing environment for dynamic spectrum rentals in accordance to an embodiment. The overview shows the interaction between a user <b>310</b>, a broker through a centralized database (CSB) <b>330</b>, operator spectrum manager <b>320</b>, a primary spectrum holder <b>107</b>, and an optional payment system <b>390</b>. In the illustrated scenario a primary spectrum holder <b>107</b> may have available spectrum that it may wish to advertise for rent. The PSH can upload this information as shown by data flow <b>335</b> directly to centralized database <b>330</b> like cloud spectrum broker. As noted earlier the functions of the broker and the centralized database can be combined into a single entity such as CSS management platform <b>103</b>. In this way the centralized database <b>330</b> is populated by PSHs advertising their spectrum for rent. Information provided by a PSH can include time, bandwidth, location, and term of use. All PSHs advertised their available spectrum by communication with the centralized database that is managed by a spectrum broker as outlined in <figref idrefs="DRAWINGS">FIG. 1</figref>. The broker may allocate the advertised spectrum to a plurality or a single operator spectrum manger <b>320</b> in conformance with a spectrum allocation policy like equally apportioning the spectrum as it becomes available. In the alternative the operators can be permitted to request a desired spectrum so it can perform their own analytics &amp; optimization as shown by process <b>325</b> and offer spectrum services to the users such as client devices. Whether the spectrum is demanded or allocated to the operator by the broker a data flow <b>340</b> between the device is shown for communicating such as allocated spectrum bundle.

p-0065Spectrum users are often interested in obtaining access to spectrum for a particular application, such as enterprise applications, two-way communications, point-to-point microwave transmissions, point-to-multipoint communications, cellular communications, mobile broadband communications, and so forth. It will be appreciated that this list is in no way exhaustive of the possible communication applications of potential users. An operator spectrum manager can request an allocation of spectrum as shown in data flow <b>340</b>.

p-0066A user <b>310</b> requesting spectrum <b>345</b> for rent would communicate with the operator acting as a broker and provides the operator with at least one time, bandwidth, location, and term of use. Additionally, through specialized messaging the operator is capable of initiating or placing advertised spectrum with a subset of users. In some instances, the user need not specify the amount of bandwidth that the user is seeking, but this information can be specified if known to the user. The operator spectrum manager (operator) <b>320</b> takes the request of user <b>310</b> and formulates a query that is sent to an internal database shown in <figref idrefs="DRAWINGS">FIG. 1</figref> as operator database <b>110</b> for processing. It is noted that query <b>345</b> can also be formulated by the operator to forecast or predict future spectrum needs by the user. Once the user's needs are interpreted and the availability spectrum for rent is interpreted, the operator database may apply algorithms to find a match between the user's spectrum need and the spectrum that is available or may be available from a primary spectrum holder as communicated by the spectrum broker. The result of the query which identifies the closest match to the request for spectrum is communicated back to the user <b>310</b> as shown by data flow <b>350</b>. Instances where the operator request a forecast for future spectrum needs, the operator engages in negotiation with the spectrum broker to meet the anticipated need for spectrum. If the spectrum suggested by the operator is acceptable to the user, the user invokes <b>355</b> a compensation system <b>390</b> that may include a transaction database and may match advertised spectrum to payments to satisfy any monetary or non-monetary consideration that is owed based on the placement of a spectrum asset. The payment system may receive compensation information from the operator or from another source, such as the spectrum user <b>310</b> or a third party.

p-0067<figref idrefs="DRAWINGS">FIG. 4</figref> is a block diagram of a distributed computing environment <b>400</b> showing a content provider, operator database, cloud spectrum service database, and client device in accordance to an embodiment. The distributed computing environment <b>400</b> provides flexible and optimal use of dynamic spectrum. Provides client devices <b>460</b> or base station <b>450</b> with superior service as spectrum requirements are met which allows the user to run all their applications whether it is video conferencing, streaming video or other internet or peer to peer applications such as video streaming from content provider <b>410</b>. A client device through base station <b>450</b> is coupled through communication network <b>105</b> which allows data to be exchanged between base stations and which provides a gateway to other networks and content providers. The communication network is a collection of different spectrum ranges held by different entities or primary spectrum holder. As shown part of the communication network <b>105</b> comprises an operator network <b>435</b>, alternate network <b>440</b> such as a government network or television station, and other networks. Exemplary candidate spectrum ranges include the 300 MHz to 400 MHz range held by the government, or the 698 MHz to 794 MHz range primarily used for television broadcasting. Each spectrum holder may wish to retain a portion of spectrum or a particular time or geography area for their continued use, and one or more wider portions of spectrum are made available for other services, such as wideband networking, video surveillance and so forth.

p-0068This allows the operator spectrum manger (operator) <b>430</b> to get spectrum from the third party like cloud spectrum broker (CSB) <b>420</b> at wholesale prices and then the operator manages the rented spectrum with its clients. This scheme is practical for two reasons: (i) The operators such as operator spectrum manager <b>430</b> can provide additional features and services. This scheme gives them control to manage the rented spectrum, perform their own analytics &amp; optimization and offer spectrum services to the clients. (ii) The demands on the third party broker such as cloud spectrum broker <b>420</b> are alleviated since it can manage spectrum at whole sale quantities and leave the finer grain device to device management to the operator. In this scheme both the operator spectrum manager <b>430</b> as well as the third party broker have to perform the analytics needed to optimize the spectrum allocations. However the granularity of these optimizations will be different. The third party broker will perform the coarse grain optimizations for spectrum allocations, while the operator performs the fine grain spectrum optimizations. The operator's spectrum manager <b>430</b> will still need to perform bi-level optimizations within the spectrum it has rented to ensure all the users in a metropolitan area have the optimal allocation.

p-0069<figref idrefs="DRAWINGS">FIG. 5</figref> is a block diagram <b>500</b> of a distributed computing environment where allocation of spectrum is split between a cloud spectrum broker and an operator spectrum manager in accordance to an embodiment. The block diagram <b>500</b> show a client device <b>510</b> (CD1 <b>510</b><i>a </i>. . . CDn <b>510</b><i>n</i>) initiating application request (R) or a request for additional spectrum <b>520</b><i>a </i>. . . <b>520</b><i>b </i>from an operator spectrum manager (OSM1 <b>430</b><i>a </i>. . . OSMn <b>430</b><i>n</i>). Each client device requires a particular amount of spectrum in order to run a communication application such as video streaming or the like. The operator network normally can provide the necessary spectrum or bandwidth to run the application; however there are instances were a higher spectrum is required or desired to achieve a target quality or resolution. The operator will then check its inventory to determine if the necessary spectrum is available for the client device. As a general matter the operator spectrum manger can acquire spectrum from a cloud spectrum broker <b>420</b>. As noted earlier the communication network <b>105</b> is a collection of spectrums belonging or associated with at least one primary spectrum holder (PSH) <b>107</b>. PSH can advertise their spectrum for rent with the cloud spectrum broker <b>420</b> which then can allocate to the operator based on some allocation policy. Each OSM translates the demand from the client device into a series of generic resource allocation or deallocation of spectrum.

p-0070By utilizing a single common cloud spectrum broker <b>420</b> which manages the allocation of resources across multiple operator spectrum managers (OSM) <b>430</b><i>a</i>, <b>430</b><i>b </i>. . . <b>430</b><i>n</i>, the CSB functions are decoupled from the operator management functions. Consequently, the OSMs may operate autonomously of the CSB once they have been allocated sufficient spectrum to run the applications at the client devices. If the CSB has to be taken offline for reconfiguring or suffers downtime, the OSM may continue processing the applications for the allocated spectrum. One advantage of this is that it improves the availability and reliability of the overall system. It should be appreciated that the CSB may typically receive multiple requests for spectrum from multiple OSMs. In response to each spectrum request, the CSB applies the spectrum allocation policy to determine whether each request may be satisfied. The CSM must keep track of the amount of spectrum that is available, since these amounts will fluctuate as spectrum are allocated, de-allocated, and as new spectrum offers become available from primary spectrum holders, as spectrum offers elapse, and as spectrum availability from the primary spectrum holders changes.

p-0071In both the operator spectrum manger and the cloud spectrum broker, an allocation service component (not shown) in cooperation with a dynamic provisioning service component provide information regarding spectrum requests that have not been met and/or spectrum that are standing idle. The dynamic provisioning service component applies various algorithms in the form of repositioning policies to determine whether to take steps to modify the make-up of the existing pool of spectrum by replenishing or releasing spectrum. For example, the dynamic provisioning service component may analyze the information regarding unmet spectrum requests and/or idle spectrum to determine whether it should, where it is possible to do so, reconfigure some of the spectrum having an attribute that is not in demand, into resources having attributes for which there is unmet demand. The particular attributes may be communication infrastructure or hardware attributes (such as bandwidth, time, or geography), operating system attributes (such as operating system type, version, patch levels, runtime operating system parameters) or application attributes (i.e. whether certain software application packages have been installed). If a set of resources meets some attributes but not others, the allocation service component, especially at the operator level, may be called upon to identify suitable candidate resources for reconfiguration.
